This invention relates to ditching machines and more particularly to such machines in which cutting discs are used for plowing ditches, forirrigation or other purposes.

Nhilea number of machines are known in the art for making ditches,.they are open to a number of objections, among which it may benoted that some machines in use will not satisfactorily ditch ground that is too i hard, that the known machines require great expenditure of power in their work, andwith some of them thereis 1n ury to crops. 1, One of the ob ects'of this invention s a ditcher of simple construction which lends itself; to economicaloperation. Afurther ob ject of this invention isthe production of a ditching machine that maybe usedforcutting ditches in any'type of groundwith" a minimum expenditure of power and a consequent increase in capacity. I a p A still further object of the invention is a ditching machine in which there is little danger of injury to crops.

' till further objects and advantages will appear from the more detailed descriptionset forth below, taken in connection with theac- 'companying drawings, but it is understood,

- that this more detailed description is given by Way of illustration and not by wayiof limitation, since various changes may be made in the construction by thoseskilled in the art, without departing from the scope] and spirit of this invention. i p

In the drawings accompanying this more detailed description, there is shown by way of illustration in r v Figure 1, a side elevationshowing the discs mounted in position on a tool holder in.

1 Figure 4, a sectional view similar to Figing thearrangernent ofldiscsshown in-Fig- Framing drawings aisthus seen'that the ditchingmachine includes cutting discs an gularly disposed withrespect to' each other, and desirably having the nearestpoint .of ap proach of these cutting discsltowardthe front of the machine, thatis, in jthe direction of.

tiavelii These cutting discs may besupplemented with anauxiliary cutting discmounted between the principal discs and cooperating-therewith.

- Turning to the more specific'iorm shown in 1 Figures 1 to 3 of the drawings, discs D, de sirablv of concave-convex form, shown at 1',

2, in Figures 1 and 20f the drawings, are also desirably provided with. an annular flange 3, forming the outer rim of these cutting discs. The d scs are mounted for rotation on the ,mountingfM', desirably a casting. f This substantially; V-shaped: mounting is provided with arms 4',-t, desirably integral with'the' mounting. "'The'disc s D, D, provided with a central opening 5, are mounted on these arms andrestagainst the abutment or shoulder 6, against which they are held by substantially 'bell-shaped bearings 7,7, The

ends of these arms 4:, tare reduced'in size toform threaded members 8, 8, on which the usualnuts 9, 9 and'wfashers' 10, lOare placed tohold the bearings '47, 7 anddiscs D, D in positionion the mounting. In'order to pro' vide for carriage, of these disos onv the ditching machine, the mounting M is recessed as shown atjll, the recess being substantial ly transverse of the main portion of, the casting and centrally located therein. v An opening 12extends from the recess 11 through the mounting and is adapted to receive a ringfbolt 13 the ring ofwhich'rests upon the recess 11; The toolholder 14 extends through the eye'iof the ring bolt 13,- the mounting being';rig'idly held in' place means of the nut 15, securedinto position on the threaded portion ofthe ring boltf- The washerlo may be, interposed between the mountingand the nut 15fi The: tool holder 14 iscarried'in the usualfmanneron the tool rail 17, of any standard cultivatorfby means'ofring. bolt v 18, spacing member or collar 19 and the nut 20, for holding these parts in their proper position. 7 7 a v V,

In the modification shown in'Figures 4 and 5 of the drawings, the discs D, D are mount-- ed in a similar manner, the mounting therefor comprising two preferably cast portions M, M, having arms 4, 4 bearings7,'7, adapted to hold the discs D, D on the arms and against the-shoulders 6, 6 of the mounte sM-t castings, M M ar e on channel irons 30, by means of bolts 31,

3l,the channel irons being spaced apart by a spacing member or casting 32, riveted; as shown at 33 to the channel irons. Ashaft 34 carried in the mountings M, M extends transversely through theispace between the channel ironsand forms the shaft on which the auxiliary disc D -revolves. Bushings 35,

V 35 are interposed between'th'e channel irons and the auxiliary disc D The mountings M, M are provided with recesses adapted to receive the said shaft 34. The outer'edge of the auxiliary disc D is desirablyjprovided 'with a shoulder 36 formed as a cutting edge.

As shown inFigure, the auxiliary disc D revolves onshaft 34 within the space between V a the principal discs D, D' and approaches I nearest to these discs D, D, angularlydisposed with respectto each other, 'at ,the nearest point of approach ofsaid discs. Y1

As shown in theassembled device in Fig-i ure 6, the modified, form of the cutting disc arrangement illustrated in Figures 4 and 5 is mounted on a suitable frame 50, provided a r with a drivers seat 51 at the rear of said frame;- The frame is supported on wheels 52 in any conventional manner. Rod 53, lever 54' and release 55 arethe usual'attachinents on such machines for depressing thecutting discs and their mountings whereby the depth ofthe ditch cut may be determined'and regulated. The channel iron 30 carrying the cutting discs is mounted out-he tongue 56, atits rearwardly extending portion 57, the tongue 56 thus forming a tool holder for thecutting Idiscs. The tongue 56 is supported from the frame by braces 58. The frame 1 may be pro-' vided'at its forward end, not shown in the drawing, with means whereby it may be pulled along the ground to be ditched. The cuttingdiscs and mountingshown 1n -F igures 1-3 maybe mounted in a similar manner on the toolrail of any standard cultivator. p

The operation of the device will be understood from the description set'forthabove. A'cultivator having the cutting discs mounted 'thereonin any manner as set forth'above, is drawn overthe groundin which a'ditch is to be cut.

As the machine progresses, the principal discs D, D or D, D: will cut into the ground thus forming a ditch.v When the modified form of the device is used, the auxile iarydisc cooperates with the main or principal discs in cutting the ditch. The cutting soil leftvbythediscs.'.- v

- lVhile as shown herein the principal discs D, 'D and D, D are preferably placed side attachment shown will ditch ground that is a toohard to be satisfactorily ditched by other models, and will also involve a considerably tor is enabled to cover more ground per day. The flange on the edge of the disc lessens the dangerof injury to crops, such as sugar beets, artichokes, potatoes, celery, etc. A machine providedwith the cutting discs herein above set forth finds wide utilityin plowing, ditch;-

ing; irrigating, ridg'ing and, cultivating lands used for raising wheat', rye, oats, corn, small gra ns 1n general, and vegetables of all.

less expenditure of power, whereby the operakinds, including those mentioned above. If a desired,lthe cutting discs may beused in conjunction with a plow or wings following the same to removethe center ridgeformed by'the cutting discs, or to remove or'pack anyloose by side, although angularly disposed, with i respect to each other, the discs may be so carried on the mounting that one follows the other. And further, while the mountings have been'de'scribed as castings, they maybe made in: any other desirable way. Again, while it is desirable to have the angularly dis posed discs with their nearest point ofapproach in the direction of travel, this is not an absolutely essential limitation, since these discs may take other angular positions with respect to each other. V i

Having thus set forth my invention, I

auxiliary disc mounted between the angularly disposed discs and cooperating therewith.

2. In a ditching machine, a pair of channel irons, amounting supported oneach channel iron, the mounting carrying disc supporting arms, the arms being angularly disposed with respect to one another, principal cutting discs mounted on the disc supporting arms, a shaftcar'ried by said mounting transversely of the space, between the channel irons, and

an auxiliary cuttingdisc mounted on said shaft and adapted to rotatethereon in thespace between the channel irons, the outer rim of the auxiliary disc extending adjacent to but beyond the point ofnearest approach of the principal discs to eachother.
